A Photo & Discussion Forum for Wharram Design Enthusiasts
Just curious if anyone has any follow up on this? Would be interested to know if you have had any issues or wear and tear on your beams from either having drain holes in the end caps or having them sealed. Been a few years since it was discussed, so seems a good time to ask about longevity either way.
Well you'll have a huge ammount of air locked up in there under the sun and the stars. That air will expand and contract every day, that means water INSIDE your beam that cannot get out. The designer specifies a vent hole with a breather tube in station 6 to vent the sealed buoyancy compartments under the floors, these are under water and away from the sun (so relatively stable temps) and if the designer thinks they need venting then we can imagine what will be the case with the beams which are under direct sunshine.
